91 Octane is a hybrid from Exotic Genetix, made by crossing Biscotti with Scotty 2 Hotty. As the name hints, people know it for a fuel-heavy smell, often with dark coffee and leather notes. It is usually listed with high THC, and reports describe a focused start that turns calm.

Where does 91 Octane come from?

91 Octane was bred by Exotic Genetix from two of its own lines: Biscotti, a sweet and gassy cross of Gelato #25 and South Florida OG, and Scotty 2 Hotty. That puts Gelato and OG genetics in its background, which helps explain the mix of gas and sweetness.

Sources don't agree on how it leans. One strain database calls it sativa-leaning, while the breeder-style copy used on retail listings calls it indica-dominant. The safest description is a hybrid, and the release date is not well documented. You may also see it written as Octane 91.

What does 91 Octane smell and taste like?

Fuel comes first, which suits the name. Retail descriptions add dark roast coffee and leather, and one strain database's flavour tags are chemical, berry and a little cheese. It's a heavier, savoury profile rather than a candy one.

One strain database's lab data lists caryophyllene first, then limonene and myrcene, though some product listings put limonene on top with humulene in the mix. Caryophyllene brings the peppery, gassy bite, limonene a touch of brightness and myrcene the earthy base. The terpene list on your package is the best guide for your batch.

91 Octane effects: what people report

People most often describe 91 Octane as focused, euphoric and energetic at first, with a calmer, relaxed body feel coming in later. A few reviews call it sleepy, and many simply call it strong. One strain database notes it's still gathering data on this one, so the picture is still early.

These are experiences people report, not promises. How it feels depends on the batch, how much you have and your own tolerance. Dry mouth and dizziness are the complaints that come up.

How strong is 91 Octane?

91 Octane is a high-THC strain. Published listings mostly sit between about 24% and 28% THC, with very little CBD.

That's a lot for a newer consumer, so start small and wait before having more. Check the THC and CBD numbers on your label, and see our guide to reading cannabis labels if the numbers are new to you.

Buying 91 Octane in Canada

Read the label for the producer and the exact name, since similar fuel-themed names like California Octane or Octane OG are different strains.

You might find it as dried flower or pre-rolls. Check the THC number, any terpene list and the packaging date, since fresher flower keeps more of that fuel and coffee smell.

91 Octane vs Biscotti

Biscotti is one of 91 Octane's parents, and both carry caryophyllene up front with gas in the smell. Biscotti leans sweeter, with cookie and nutty notes, and people often describe it as relaxed and giggly. 91 Octane pushes harder on fuel, coffee and leather, and is more often called focused before it settles. If you want sweetness with your gas, pick Biscotti. If you want the gas turned up, try 91 Octane.

Highest THC strains: what the numbers really meanThe highest THC strains are the ones with the biggest Total THC number on a lab report, but that number is a ceiling that varies by batch, lab and method. This guide explains how THC is measured and labelled in Canada, why very high figures are often inflated, and why a higher number isn't automatically a better choice.How to use a weed grinder (and clean it)A grinder breaks dried flower into small, even pieces by twisting two toothed halves against each other. Load the buds, close the lid, twist back and forth, then open it to collect the ground flower, and wipe or soak it clean every so often so resin doesn't gum up the teeth.Pre-rolls explained: what's inside, sizes, and infused pre-rolls in CanadaA pre-roll is a joint rolled and sealed by the producer: ground cannabis in a paper cone, usually with a cardboard crutch, sold in a tube or multi-pack. Sizes commonly run from about 0.3 g to 1 g. In Canada, Health Canada treats an infused pre-roll as a cannabis extract product, not dried cannabis.
